在jQuery動畫功能中的步驟

我正在使用jQuery動畫中的步驟來動畫CSS轉換屬性。什麼時間限制，我保留動畫功能，沒有考慮到。我的代碼是這樣的在jQuery動畫功能中的步驟

$('#instructions').animate({now:'+=50'},{ 
    step: function(now) { 
     $(this).css('transform','rotate('+now+'deg)'), duration:'slow' 
    } 
},50000);

我在這裏我的旋轉格約50度與50000ms的時間跨度，但它不是採取這些50000ms。我能做些什麼來創造那個時間跨度。在此先感謝。

這是我的HTML。

我正在使div旋轉像擺鐘。

@ chiapa，我已經發布在問題中的目標HTML，對不起，我不能給你一個小提琴 – Jayababu

您正在使用.animate與不正確的參數 - 你試圖傳遞一個duration和options不存在。你打電話或者使用：

.animate(properties [, duration ] [, easing ] [, complete ])
.animate(properties, options)

如果使用第二個版本，那麼你需要設置options對象內部duration財產。

這工作：

$(document).ready(function(){ 
 
    var animDuration = 1000; 
 

 
    $('#instructions').animate({ now: '+=50' }, { 
 
     duration:animDuration, 
 
     step: function(now,fx) { 
 
      $(this).css('transform','rotate('+now+'deg)'); 
 
     } 
 
    }); 
 

 
    $('#instructions').animate({ now: '-=100' }, { 
 
     duration:animDuration, 
 
     step: function(now,fx) { 
 
      $(this).css('transform','rotate('+now+'deg)'); 
 
     } 
 
    }); 
 

 
    $('#instructions').animate({ now: '+=50' }, { 
 
     duration:animDuration, 
 
     step: function(now,fx) { 
 
      $(this).css('transform','rotate('+now+'deg)'); 
 
     } 
 
    }); 
 

 
})

值得注意的是，因爲OP使用'step'回調來做動畫，如果動畫在jQuery中被全局禁用，元素將不會' t最終會落到最後的位置。這裏沒有問題，因爲最終的位置回到了它開始的地方。 –
